Interventions
- BehavioralSmart Walk
Smart Walk is a culturally tailored, Social Cognitive Theory-based multi-component smartphone delivered physical activity (PA) promotion intervention that delivered through the Smart Walk application, virtual physical activity coaching, and text messages. The Smart Walk smartphone application includes four key features: 1) personal profile pages, 2) culturally relevant multi-media physical activity promotion modules, 3) discussion boards, and 4) physical activity self-monitoring/tracking feature that integrates with Fitbit activity monitors for participants to track their daily, weekly, and monthly activity. Virtual physical activity coaches will actively engage and facilitate group-based dialogue among participants on the app discussion boards and provide individualized, one-on-one PA coaching via telephone or commercially available app-based video teleconferencing software (i.e., FaceTime, Zoom, Google hangouts).
